The dip at a place is delta. For measuring it, the axis of the dip needle is perpendicular to the magnetic meridian. If the axis of the dip needle makes angle θ with the magnetic meridian, the apparent dip will be given tanδ1 which is equal to: the apparent dip will be given tanδ1 which is equal to: the axis of the dip needle is perpendicular to the magnetic meridian.
